Improvement in earth-closets



HENRY CLARK, OF BALTIMORE, MARYLAND.

IMPROVEMENT IN EARTH-'CLQSETS.

Specification forming part of Letters Patent No. 132,862, dated November5, 1872.

To all whom it may concern:

Be it known that I, HENRYCLARK, of Baltimore, in the county of Baltimoreand State of Maryland, have invented a new and Improved Earth-Closet, ofwhich the following is a specification:

Figure l is a detail vertical section of my improved earth-closetclosed, taken through the line a m of Fig. 2. Fig. 2 is a top view ofthe same closed, the cover being removed, and partly in section throughthe line 3 y, Fig. 1. Fig. 3 is a detail vertical section of the sameopened for use, taken through the line 2 a, Fig. 4. Fig. A is ahorizontal section of the same opened for use, taken through the line tow, Fig. 3.

Similar letters of reference indicate correspondin g parts.

The invention consists, first, in providing the vibratory shaft of anearth-closet hopper-valve with a spring-retracted horizontal rod,arranged and operated as hereinafter described. It consists, secondly,in the peculiar construction and arrangement of a lock-bar and catch,which are' used in connection with the hopper.

A represents the case of the earth-closet, which is made in the form ofa washstand or bureau. The lower part a of the front of the case A ismade in one piece, is hinged at its lower edge to the forward edge ofthe bottom of said case A, and has cleats a attached to its inner sideto serve as ways or guides to the receiver B, when being drawn out andpushed in. The receiver B should be mounted upon small wheels orrollers, to enable it to be moved in and out easily. 0 is the lower orsmall hopper, which is supported from the case A in such a position thatits bottom may be just above the receiver B when said re- 'ceiver ispushed in, and the discharge-opening of the said hopper directly abovethe opening in the top of said receiver, so that the earth from the saidhopper 0 may pass directly into the said receiver. The discharge-openingof the hopper C is closed by the door or valve D, one edge of which isrigidly attached to the shaft E, so that the said door may be closed andopened by turning the said shaft E. The shaft E has a crank, 6, formedupon one end, the arm of which enters a hole in the rod F, so that thedoor of valve D may be closed or opened by the longitudinal movement ofthe said rod F. The rod F passes through and works in holes in the frontand rear sides of the case A. G is a coiled spring, placed upon the rodF to hold the said rod forward, and thus hold the door or valve D closedor raised. The forward end of the rod F projects at the forward side ofthe case A in such a position that the door a when closed will strike,against it and force it back, opening the door or valve D, and allowingthe earth in the hopper (l to fall into the receiver 13. H is the upperor larger hopper, that contains the supply of earth. Thedischargeopening in the bottom of the hopper H is closed by a door orplate, I, attached to the upper part of the small hopper O in such aposition that when the said hopper H is fully pushed back the saiddisch. rge-opening will be closed, and when the hopper H is drawnforward a little way the discharge-opening will be opened sufficientlyto allow a small quantity of earth to pass down into the small hopper G.The-hopperH has a bar, J, pivoted to its lower forward part, whichpasses out through a slot in the lower part of the stationary forwardside of the case A that is overlapped by the upper part of the door aand which has a hook or shoulder formed upon the lower side of itsforward end to catch upon a catch, K, attached to the inner side of theupper part of the door a so that the hopper H may be drawn forward tosupply the hopper 0 with earth by opening the said door a. Upon thelower side of the bar J is formed an incline, which, as the hopper H isdrawn forward, strikes upon the lower end of the slot in the case A,through which the saidbar J passes, and thus raises the forward end ofthe bar and disengages it from the door 60, when the hopper H has beendrawn forward to the desired point. To the forward side of the hopper Hare attached arms or bars L, which, when the said hopper has been drawnforward, project through slots in the case A, so that the door a whenbeing closed, may strike against their projecting ends and force thesaid hopper back to its place. The hopper H may be operated by thereceiver B instead of the door a if desired.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination of the crank 6, rod F, and springG, with the shaft E of the valve D of the small hopper O, substantiallyas herein shown and described, and for the purpose set orth.

masses 2. The combination of the pivoted bar J, constructed asdescribed, and catch K with the hopper H, case A, and door asubstantiaily as and for the purpose set forth.

HENRY CLARK.
